I'm trying to debug it, it gaves me this error:

Unable to compile 'get_image_url': Global symbol "$table_Files" requires explicit package name at (eval 28675) line 15. Prova-2

so i tried to declare:
$table_Files |= "Links_Files"

i also tried changing "$table_Files" to "Links_Files",

but it gives still the same error...i'll let you know...
